Koonaa Fathead - Film/Film, Carbon /Technora
The EPEX layout, with optimum fiber distribution allows us to build a stable and efficient Square Top. An optimum designed square head provides easy trimming and control. When the wind increases, the top of the sail will twist, and the result is a flatter sail. In light wind the extra area gives the boat more power. The square head mainsail has full battens, which in addition to making the sail stable when sailing also makes the sail pack itself when lowering it in to your zippack.
Material
The film/film is a light-weight high-performing membrane. The Carbon / Technora fiber combination is an optimal solution in terms of shape and performance.
Performance - Durability - Price
Performance, durability and price indicators are illustrated for each material combination on a scale from 1-10, 10 being the highest. Use the performance, durability, and price parameters as indicators only, and to compare various material to one another.

Conventional Main - short battens
Sail Type
The conventional mainsail with short battens still has full top batten. Having shorter battens in the lower parts of the sail makes the trimming and depowering easier. Short battens also make the sail weigh less and is normally the preferred choice for racing. Short battens also mean less chafe against the rig and spreaders when sailing downwind, so it should be considered if you plan to cross the oceans and sail downwind for long distances.
The sail can be delivered with slides or luff rope, reefs and all other necessary options, for instance: trim stripes, sail numbers, cunningham, over-head leech line, loose foot and sail bag.
Layout
Available in cross-cut, trioptimal and EPEX.
When to use
The conventional mainsail with short battens can be used in all weather conditions – upwind and downwind. For heavy wind conditions the sail area can be reduced by reefing. -
Conventional Main - full battens
Sail Type
The horizontal full battens in the conventional mainsail help keep the shape of the sail, and when lowering the sail, it practically packs itself into the lazy jack or zippack. As the sail is easy to use and stable, it is a favorite sail for many cruisers.
The sail can be delivered with slides or luff rope, reefs and all other necessary options, for instance: trim stripes, sail numbers, cunningham, over-head leech line, loose foot and sail bag.

In-Mast Furling Main - no battens
Sail Type
This is the simplest in mast furling mainsail. Cost effective and solid are the most important features. It is possible to furl into all furling masts, also the ones with a narrow opening.
Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trim stripes and other options are also available.
Layout

When to use
The in-mast furling mainsail with no battens can be used in all weather conditions – upwind and downwind. For heavy wind conditions the sail area can be reduced by furling in the sail partly. -
In-Mast Furling Main - short battens
Sail Type
This in-mast furling mainsail with short battens can be built with a straight leech which gives a larger and more efficient sail than without the battens.
Normally this sail will also fit into all masts, also the ones with narrow opening, as the battens are flat. It is a cost effective and solid sail. Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trim stripes and other options are also available.

EMS Main
Sail Type
The EMS is an in-mast furling mainsail with full continuous vertical battens. The continuous vertical battens with carbon top provide support for the leech, whether the sail is fully deployed or reefed. The battens are also to be used as reefing points, stretching the reefed luff and making the sail flat and efficient.
Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trim stripes and other options are also available.

EMS Max Main
Sail Type
The EMS max sail is the cruising in mast furling mainsail that also win races. The sail area can be designed as a conventional mainsail, but with several extra features.
The continuous vertical battens with carbon top provide optimal support for the leech, whether the sail is fully deployed or reefed. The short intermediate battens have the same function. The full battens are also to be used as reefing points, stretching the reefed luff and making the sail flat and efficient.
Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trim stripes and other options are also available.

The FatFurl in mast furling mainsail, only available at Elvstrøm Sails, is specially designed with optimum shape and maximum sail area for all modern High-Performance Cruisers.
The FatFurl is larger than a conventional horizontally battened mainsail.
The continuous vertical battens with carbon top provide maximum support for the leech, whether the sail is fully deployed or reefed. The full battens are also to be used as reefing points, stretching the reefed luff and making the sail flat and efficient. The short intermediate battens have the same function. The EPEX layout ensures an optimum fiber distribution and a strong and stable sail.
Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trimstripes and other options are also available.

In-Boom Furling Main
Sail Type
The in-boom furling mainsail is custom made for all furling boom types.
The horizontal full battens help keep the shape and ensure that the furling into the boom runs without problems. The lowest battens are also working as reefing point as they stretch out the reefed down mainsail.
Normal options to include are top UV cover, reefing marks, sail bag, sail number, trim stripes, and other options are also available.
Layout
Available in crosscut, trioptimal and EPEX.
When to use
The in-boom furling mainsail can be used in all weather conditions – upwind and downwind. For heavy wind conditions the sail area can be reduced by furling the sail partly in to the boom.
